first tune not so good

So i had a couple problems, some bad some not so bad.

1st- My intercooler was leaking (solved for now)
2nd- My mbc wasn't working right. boost was up and down
3rd- 2 spark plugs were cracked!
4th- Tune was not completed because i need to figure out another issue. He said my timing was jumping across the map. He said maybe its bad gas or I need to do a compression test. Which i am doing tomorrow.

Spark plugs don't just crack. Find out why. Look carefully at fueling vs. timing because I can't imagine how this happened otherwise.

You can do a compression test on a cold motor but you generally want to add some oil to the cylinders first. You don't want to do it dry. You can just pull the fuel pump relay and crank the motor over a couple times. But you do get more accurate results on a warm motor.
